Ocean Biogeochemistry and Air-Sea Interactions II


Session ID#: 36694

Session Description:
Studies of ocean biogeochemistry related to air-sea interactions are providing significant new information to help us understand a wide variety of physical, chemical and biological processes in the oceans. There are many processes that link the surface ocean and the lower atmosphere, for example, the release of biogenic compounds as sources of cloud or ice condensation nuclei, the deposition of natural and anthropogenic aerosols that can affect plankton communities, the transport of airborne microbes that can alter the dynamics of proximal and distant ecosystems, the biology, chemistry and physics of the sea-surface microlayer (SML) as the interface through which all exchanges between the atmosphere and the ocean occur, the enrichment of surfactants and other biogenic compounds in the SML that can affect gas exchange rates, etc. Understanding these processes is crucial for improving the reliability of regional and global models and the evaluation of future scenarios. We welcome contributions on all aspects of the physics, chemistry, and biology of air-sea interactions, including observations, experimentation, methodological or technical developments, and theoretical and modeling efforts.
